Devilish Bloodline

Your magic comes from devilish powers that was mixed with the blood of you or your ancestors. It could've come from an ancient pact with an archdevil, or maybe even a devil ancestor. Any sorcerer could be the first in a new bloodline, or they could be the descendants of an ancient and powerful magic-user.

Devilish Resistance

As magic flows through your body, it causes physical traits of your devil ancestors to emerge (ex. horns, tail).

Additionally, you have resistance to fire, and your skin temperature is warmer than usual.

Fire Affinity

Starting at 6th level, when you cast a spell that deals fire damage, you can add 1d4 points of fire damage to that spell. This changes to 2d4+2 at 14th level and 3d4+3 at 18th level.

Devil Wings

At 14th level, you gain the ability to sprout a pair of devil wings from your back, gaining a flying speed equal to your current speed. You can create these wings as a bonus action on your turn. They last until you dismiss them as a bonus action on your turn.

You can’t manifest your wings while wearing armor unless the armor is made to accommodate them, and clothing not made to accommodate your wings might be destroyed when you manifest them.
